5. Plug the ac power cord into any standard AC outlet.  
NOTE: The radio automatically disconnects internal batteries when you

CONNECTING AN EXTERNAL ANTENNA  
FOR BETTER AM RECEPTION:  
Your radio has a built-in AM antenna for reception of strong, local  
broadcasts. For improved reception, you can connect an external AM  
antenna. Your local RadioShack store has a wide selection of AM antennas.  
To connect an external AM antenna to your radio, use a Philips screwdriver  
to loosen the screw on the external antenna terminal, slide the external  
antenna's spade lugs underneath the screw head, then tighten the screw.  
FOR BETTER FM, TV, OR UHF RECEPTION:  
Your radio has a telescoping antenna for FM, TV, and UHF reception.  
NOTES:  
When you use the telescoping antenna for FM or TV reception, be sure  
the metal straps are connected.  
When you use the telescoping antenna for UHF reception, be sure the  
metal straps are connected.  
For improved reception, you can connect an external antenna. Your local  
RadioShack store has a wide selection of antennas.  
Follow these steps to connect an external FM, TV, or UHF antenna to your  
radio.  
1. Use a Philips screwdriver to loosen the screws on the external antenna  
terminals.  
2. Slide the external antenna's spade lugs underneath the screw heads,  
then tighten the screws.  
NOTE: When you attach both external FM/TV and UHF antennas, be sure  
 
the metal straps are connected as shown.

Operation  
Faxback Doc. # 37835  
OPERATING THE RADIO  
WARNING: To protect your hearing, turn VOLUME to its lowest setting before  
you turn on the radio.  
1. Push in POWER to ON.  
2. Set FM/AM/TV to the desired band. If you selected the TV band, set TV  
BAND to the desired setting.  
3. Rotate the tuning knob to select the desired station.  
NOTES:  
To precisely tune to a weak FM station using automatic frequency  
control, slide AFC to OFF. Rotate the tuning knob to select the  
desired station, then slide AFC to ON for drift-free reception.  
For the best FM, TV, and UHF reception without connecting an external  
antenna, extend the telescoping antenna to its full length.  
For AM stations, rotate the radio to the position that provides the  
best reception.  
4. Adjust TREBLE, BASS, and VOLUME for the best sound.  
5. To turn off the radio, push POWER to OFF.  
USING AN EARPHONE  
For private listening, plug a monaural earphone (not supplied) with a 1/8  
inch plug into the EAR jack on the right of the radio. This automatically  
disconnects the built-in speaker.  
Your local RadioShack store carries a wide selection of earphones.  
LISTENING SAFELY:  
To protect your hearing, follow these guidelines when you use an earphone.  
 
Set the volume to the lowest level before you begin listening. After  
you begin listening, adjust the volume to a comfortable listening  
level.  
Do not listen at extremely high volume levels. Extended high-volume  
listening can lead to permanent hearing loss.  
Once you set the volume, do not increase it. Over time, your ears  
adapt to the volume level, so a volume level that does not cause  
discomfort might still damage your hearing.  
TRAFFIC SAFETY:  
Do not wear an earphone while operating a motor vehicle or riding a  
bicycle. This can cause a traffic hazard and is illegal in some areas.  
Even though some earphones are designed to let you hear outside sounds when  
listening at normal volume levels, they still present a traffic hazard.

Your Optimus Portable 5 Band Radio is an example of superior design and  
craftsmanship. The following suggestions will help you care for the radio  
so you can enjoy it for years.  
Keep the radio dry. If it gets wet, wipe it dry immediately. Liquids

Temperature extremes can shorten the life of electronic devices,  
damage batteries, and distort or melt plastic parts.

of parts.  
Handle the radio gently and carefully. Dropping it can damage  
circuits boards and cases and can cause the radio to work improperly.  
Use only fresh batteries of the required size and type. Old batteries  
can leak chemicals that damage your radio's electronic parts.  
Wipe the radio with a damp cloth occasionally to keep it looking new.  
Do not use harsh chemicals, cleaning solvents, or strong detergents to  
clean the radio.  
Modifying or tampering with the radio's internal components can cause a  
malfunction and might invalidate your radio's warranty and void your FCC
